It's actually loading the firmware for the cx25840 that is so slow. So
yes, this is normal, unfortunately. I strongly suspect that it can be
sped up, but I never had the chance to really look at it and do the
calculations. I will never be fast, though, since the firmware has to
be uploaded via the i2c bus, which is notoriously slow. It really isn't
suited for firmware in my opinion.
